WACO, Texas — Perry Jones needed 13 seconds to record his first field goal, a lob dunk that happened before Baylor fans had even settled into their seats.

For the remaining 39:47 against Kansas, the Big 12’s preseason player of the year was a non-factor. Jones finished with five points and three rebounds in KU’s 68-54 victory, going 1-for-8 from the floor in 25 minutes.

“I think Perry just missed shots, and I think he got down after he missed shots,” Baylor coach Scott Drew said.

KU played a role in this, though the Jayhawks didn’t devise any inventive defense to contain the 6-foot-11 sophomore.

Thomas Robinson, who drew the initial assignment, fronted Jones in the post and eliminated any easy catches. Robinson didn't have a huge offensive game by his standards — 15 points, 11 rebounds — but his physical defense was a factor in keeping Jones off balance.

“Thomas played great defense,” center Jeff Withey said. “Thomas played straight up on him a lot of the time and forced him to take awkward shots.”

Jones wasn’t the only Baylor starter who struggled against KU’s defense.

Brady Heslip, hounded by Elijah Johnson, recorded zeroes across the box score with only two shot attempts, and Quincy Miller went scoreless after hitting his first shot.

“For those guys not to score from the field after that, I would never have thought that would happen,” coach Bill Self said. “That was obviously a big blow for them and a big help for us.”

Baylor shot 37 percent as a team to 51 percent for KU. Self hasn’t been thrilled with KU’s defense lately, but it was hard to find much fault in Wednesday’s performance.

“To be honest, I don’t think we’ve guarded for three weeks,” Self said. “I don’t think we have. But it’s what we believe. It’s got to be the staple of who we are.”

If you want to nitpick, though, Jones did have that one basket.

“I could have strangled our guys,” Self said. “We knew they were going to come out and run ball-screen, back-screen and run that play. We went brain dead.”

JOHNSON STILL COLD

Elijah Johnson went 0-for-6 from the field for his second scoreless game of the season.

Johnson continues to search for his shot — especially from 3-point range, where he was 0-for-4 — but it didn’t inhibit KU’s offense in any noticeable way.

“The two guard, he can’t buy one right now,” Self said. “Still, the guys ran good enough offense they were able to get some easy baskets. That’s pretty remarkable to me, (shooting) above 50 percent when the two guard’s not making shots. I know he will.”

Travis Releford didn’t offer much offense, either, scoring one point in 24 minutes.

Conner Teahan played significant stretches of the first half and burned Baylor's zone for two 3-pointers.
